Substitute Part Grouping Explanation

Substitution eligibility for the V480LS40APX2855 is determined by strict equivalence across the following critical parameters:

• Varistor voltage rating (675 V – 825 V range, 750 V typical)
• Surge current capacity (4.5 kA)
• Energy absorption (105 J)
• Mounting configuration (Through Hole)
• Physical form factor (Disc 14mm)
• Number of circuits (1)
• Operating temperature range (-55°C to 85°C)
• Compliance certifications (ROHS3, REACH Unaffected)

The V480LS40AP qualifies as a parametric equivalent substitute. Both parts share identical electrical specifications and mechanical dimensions. The distinction lies exclusively in packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is available in Cut Tape (CT) format. This packaging difference does not affect component performance, functionality, or circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the V480LS40APX2855 and V480LS40AP are active production components with identical electrical performance and mechanical compatibility. Selection between these parts should be based on procurement requirements and assembly processes:

The V480LS40APX2855 in Tape & Reel format is suitable for high-volume automated assembly operations where reel-fed component handling is standard.

The V480LS40AP in Cut Tape format accommodates lower-volume production runs, manual assembly processes, or situations where individual component access is required without reel infrastructure.

Both parts maintain full ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment across all applications. The identical operating temperature range, surge current capacity, and energy absorption characteristics guarantee functional interchangeability in circuit design.

Frequently Asked Questions (FAQ)

Q: Can V480LS40AP be used as a direct replacement for V480LS40APX2855?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Cut Tape versus Tape & Reel). Circuit performance and component specifications are unchanged.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging supplies components on continuous reels suitable for automated pick-and-place assembly equipment. Cut Tape packaging provides components on tape segments, typically used for manual assembly or lower-volume production. Both formats contain the same component with identical specifications.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical ROHS3 compliance and REACH unaffected status. Moisture sensitivity level, ECCN classification, and HTSUS codes are identical.

Q: What determines whether a varistor can substitute for the V480LS40APX2855?

A: Substitution requires matching across all critical parameters: 750 V typical varistor voltage (675 V – 825 V range), 4.5 kA surge current, 105 J energy rating, through-hole mounting, 14mm disc form factor, single circuit configuration, and -55°C to 85°C operating temperature range.

Q: Can I use these parts interchangeably in my PCB design?

A: Yes. Both parts have identical through-hole mounting specifications and 14mm disc dimensions. PCB footprints and lead spacing are identical, enabling direct substitution without design modification.
